A few more notes. The major oil companies cannot take full advantage of percentage depletion or intangible drilling costs, only smaller companies.
The manufacturing deduction is available to all US manufacturers. If we get rid of this deduction for oil companies, we should do the same for all manufacturers.
An alternative perspective is that these tax preferences are similar to the tax preferences all businesses receive (ie. being able to deduct certain expensive, etc.). We should reform the tax code, but do so for all businesses. More here: http://instituteforenergyresearch.org/analysis/the-obama-adm...
